Strange Question......I guess hotter magma rises to the surface of the mantle while colder magma sinks closer to the center....Sort of like a lava lamp!

When you plug in a lava lamp, it heats up at the bottom, just like the earth's magma. It's hot at the bottom and it cools at the top.

There's no fun in playing it safe. Why not try something a little unhinged?

The Earth's mantle is a solid layer of rock beneath the Earth's crust, whereas a lava lamp contains liquid wax that constantly moves around due to heat from a light bulb underneath. The mantle is a natural geological feature of the Earth, while a lava lamp is a decorative household item.

Lava Lamp:

  • requires an external electrical heat source
  • man-made
  • constructed of glass and metal
  • paraffin inside moves quickly relative to magma in mantle
  • can be purchased
  • is transportable
  • comes in a variety of colors
  • easily observable
  • required temperature of operation less than 200o F

Earth's mantle:

  • occurs naturally
  • powered by Earth's internal heat
  • consists largely of ultra-mafic rock
  • temperatures can reach 4000o F
  • cannot be purchased, observed directly, or transported
  • is rather large compared to lava lamp, comprising 83% of Earth's total volume
  • movement of rock is extremely slow compared to movement of paraffin in lava lamp

Sometimes it can be the colours (red or orange) but its mostly the wax is meant to look like lava hence lava lamp.

A lava lamp has wax, oil, and water in it when all three of those things heat it is called convection. The three elements move all around.
